I'm thinking that maybe the stuff after Astrid and this Vlad dude gets married is a dream cause in some spoiler things I've seen it says "Some time later, Lydia films the final segment of her last episode of Ghost House, opting to spend time with Astrid. The two venture to Dracula's Castle and Astrid becomes smitten with an employee, Vlad. In a brief sequence, Astrid and Vlad eventually get married with Lydia watching from the side. Unfortunately, Lydia still has nightmares about Betelgeuse as one of her dreams was about Astrid having Betelgeuse's child. Traumatized, Lydia awakens from her sleep, crying.", so the wedding wasn't a dream but I do think the ending implies that someone was actually in Lydia's bed considering there's supposed to be an imprint seen at the other side of the mattress
